On Riccati Equations in Banach Algebras [PDF]

open access: yesSIAM Journal on Control and Optimization, 2011
Let $R$ be a commutative complex Banach algebra with the involution $\cdot ^\star$ and suppose that $A\in R^{n\times n}$, $B\in R^{n\times m}$, $C\in R^{p\times n}$. The question of when the Riccati equation $$ PBB^\star P-PA-A^\star P-C^\star C=0 $$ has a solution $P\in R^{n\times n}$ is investigated.

On the Use of Low-Order Riccati-Equations in the Design of a Class of Feedback Controllers and State Estimators [PDF]

open access: yesModeling, Identification and Control, 1980
This paper describes a method for designing optimal feedback controllers with stability requirements using low-order Riccati equations. For originally stable systems the Riccati equation will be of first or second order, depending upon whether the ...
